TABLE.

Application filed September 17, 1919. Serial No. 324,260.

To all 107mm it may concern."

Be it known that I EDWARD H. ANGLE, a citizen of the United States,'anda resident of Pasadena, in the county of Los Angeles, State ofCalifornia, have invented certain new and useful Improvements in Tables,of which the following is a specification, reference being had to theaccompanying drawings.

My invention relates particularly to tables employed by dentists,surgeons or other such professional practitioners for carrying withineasy reach the tools, implements, materials and devices as may berequired whileoperating, and is especially directed to tables adaptedfor the practice of orthodontia.

The principal object of my invention is to provide a table that may bemoved lineally toward and away from the patient in the chair, into themost convenient position for the needs of the operator.

Other object of my invention are to provide a table that may be movedwith minimum effort, that will move smoothly to avoid displacingimplements or materials supported thereon, and that will maintainadefinite relation to the chair irrespective of its distance therefrom.

My invention comprehends a table having a portable base upon which itmay be rela tively reciprocated in parallel relation to the plane ofsaid base.

The form of my invention as hereinafter described, comprises a tablehaving an elongated top disposed transversely to the centrallongitudinal plane of an operating chair, and provided with spaced legsor standards having casters or rollers arranged to traverse suitablyspaced tracks extending parallel with said plane, on a portable baseboardplate. Said rollers and tracks coiSpcrating to maintain a smoothand easy movement of said table toward and from said chair,'in a linealdirection.

My invention also includes all of the various novel features ofconstruction and arrangement as hereinafter more definitely dulydistracting his attention.

' base, taken on the line 3--3 in Fig. 1, and

conveniently showing a fragment of the right hand leg. T

in said figures the table comprises the top or tablet '1, legs 2 and 3terminating in feet 4 and 5, and the base 6, which is preferably ed torotatein suitable bearings 10 and 11,

and to traverse tracks 12 and 13 which may preferably be formed of strapmetal inlaid in said base 6, with their exposed surfaces flush with thetop surface of said base.

As shown in Figs. 1 and 2, the left-hand track 12 is provided with asmall rib 15 extending longitudinally thereof, and arranged to engage inthe grooves 16 in the rollers 7, and cotiperate therewith to guide themovement of the table in a lineal path, and to consequently cause theplain faced rollers 8 to traverse the plane surface of the right-handtrack 13, as shown in Figs. 1 and 8.

The lineal movement of the table is arranged to be effected in parallelrelation to the longitudinal plane of the operating chair, whose axis isindicated by the vertical dot and dash line 19 and whose circular baseis indicated by the elliptical dot and dash line 20, the table base 6being pro- I vided with the semi-circular indenture 22. for theconvenient reception of said chair base, thus affording a greater rangeof movement of the table toward the patient in the chair, and therebypermitting the operator to utilize the table as an arm-rest, which is tobe desired in the delicate and tedious operations incident to thepractice of orthodontia.

It may be here noted that in the practice or orthodontia, it may benecessary to move the table toward and from the operating chair manytimes during a single visit of a patient, and that in order that thetable may be most convenient for the use of the operator, it must becapable of being moved forward and backward in a definite relation tothechair, in the easiest possible manner, so that the operator mayinstantly gain access to his instruments without un- Furthermore, thetable must move smoothly so as to avoid displacing the instruments ormaterials which may be supported thereon.

made therein without departing from the with'the foot of the operatorwhose operatin position is at the right of the chair.

T do not desire to limit my invention to the precise details ofconstruction and arrangement as herein set forthyas it is obvious' thatvarious modifications may be essential features of my invention asdefined in the appended claims.

Having thus descirbed my invention, I claim:

1 A table having a portable base, and provided with legs having rollers;the rollers of one leg being grooved, While the rollers of the other leghave plain cylindrical surfaces; spaced tracks in the surface of plainsurface rollers may roll, and the other having a longitudinally extendedrib engaged in the groove of said grooved rollers.

2. A table having a base, and provided with legs having rollers arrangedto traverse the surface of said base in a lineal direction, said basehaving an indenture in one side thereof for the reception of the base ofan operating chair with which said table may cooperate, and tracks insaid table base for said rollers, extended-to embrace said chair base.

In witnessvwhereofl have hereunto set my hand this 11th day ofSepternper, A; D. 1919.
